(54) SYNTHETIC RESIN THRUST SLIDING BEARING


(57) A synthetic resin-made thrust sliding bearing comprising a synthetic resin-made upper casing which includes an upper annular plate portion, an outer cylindrical portion, and an inner cylindrical portion; a synthetic resin-made lower casing which is superposed on said upper casing so as to be rotatable with respect to said upper casing and, which includes a cylindrical portion; a synthetic resin-made thrust sliding bearing piece which integrally includes an annular plate portion in contact with the upper annular plate portion of said upper casing and the cylindrical portion of said lower casing, respectively, and a cylindrical portion interposed between the inner cylindrical portion of said upper casing and cylindrical portion of said lower casing; an outer elastic seal member which is in contact with an outer surface of the cylindrical portion of said lower casing at an inner elastically deformable lip portion thereof formed integrally on a cylindrical inner surface thereof in such a manner as to project diagonally inwardly and upwardly from the cylindrical inner surface, which is in contact with an inner surface of the outer cylindrical portion of said upper casing at an outer elastically deformable lip portion thereof formed integrally on a cylindrical outer surface thereof in such a manner as to project diagonally outwardly and downwardly from the cylindrical outer surface, and which is in contact with an annular stepped surface of the outer surface of the cylindrical portion of said lower casing, at annular lower surface thereof, respectively; and an inner elastic seal member which is in contact with an inner surface of the cylindrical portion of said lower casing at an outer elastically deformable lip portion thereof formed integrally on a cylindrical outer surface thereof in such a manner as to project diagonally outwardly and upwardly from the cylindrical outer surface, which is in contact with an outer surface of the inner cylindrical portion of said upper casing at an inner elastically deformable lip portion thereof formed integrally on a cylindrical inner surface thereof in such a manner as to project diagonally inwardly and downwardly from the cylindrical inner surface, and which is in contact with an annular stepped surface of the inner surface of the cylindrical portion of said lower casing at annular lower surface thereof, respectively.
